I have a filtered fish tank and i change the water about every 1-2 weeks. But it seems like right after I change it, like 1-2 days, this film appears on top of the water. It almost looks kinda slimy. It makes me think I didn't do a good job cleaning the tank (i spend about and hour doing it and i'm pretty sure i do a good job) and I even use filtered water to fill the tank. Is this slimy stuff okay for the fish or is it unhealthy? Is my filter/tank not working properly? Or is this just perfectly normal?
